AI Video Prompt: Penguin Desert Slide

Create an 8-second vertical 9:16 cinematic 3D animated video. A cute baby penguin with large glossy eyes, black and white fluffy feathers, orange feet, and a small blue backpack stands on the top of a golden desert sand dune. The video begins with a close cinematic shot of the penguin looking curious in the warm sunlight. The penguin starts moving and accidentally slides down the smooth sand dune. It moves naturally with gravity, slightly rolling and using its small wings for balance. The camera smoothly tracks the penguin as it slides down. Sand particles move realistically around its body. After reaching the bottom, the penguin stands upright, looks toward the camera, smiles, and raises its wings happily. Maintain Pixar-inspired 3D animation quality, realistic desert lighting, soft shadows, cute emotional expression, consistent character design, and natural physics. No dialogue. Use soft desert ambience and sand movement sounds. No extra characters, no changes in character appearance, no unrealistic movements.
